Where do you find the code for the radio in your Renault megane scenic?
Radio Code you can find in the service book. Search for the symbols C.A.R and four digits near must be a code.
Guglielmo Marconi (Marchese Guglielmo Marconi), an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899, he flashed the first wireless signal across the English Channel, and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful trans-Atlantic radiotelegraph. Wikipedia has a good article on this Nobel Prize winner, and a link is provided.
A piece of apparatus that makes electromagnetic waves at radio frequencies (above 30Hz to less than 300GHz). Almost always this stream of waves is made to carry information of some kind in some way, a process known as modulation. The information could be just sound, or television, or telephone conversations, and or various other things. The simplest forms of modulation vary the radio waves' amplitude or frequency is step with the information that must be carried.
Can you use your satellite radio antenna for your gps?
No, you can not use any satellite radio to connect to Sirius. The hardware for each (XM or Sirius) is designed specifically for one or the other. For Sirius, there is a code on the back of the radio that they need to activate the service. It is specific only to Sirius equipment.
How does a crystal radio work?
This contributor finds it easiest to understand the following explanation.
Fasten your seat-belt; it may be a bumpy ride:
The basic principle to keep in mind is this:
When you pass more than one frequency through any non-linear device, the frequencies
get "mixed". What comes out the other end is the original frequencies PLUS the sum-
frequency and the difference-frequency of every possible combination of the original ones.
Remember this.
A non-linear device can be anything that conducts current better in one direction
than it does in the other direction. Like a semiconductor diode. Or a sharp-pointed
wire touching some varieties of naturally-occuring minerals, which are called "crystals"
when they're used in simple hobby radio kits.
Start at the radio transmitter:
-- The transmitter generates a "carrier" wave, at the frequency where it'll show up
on your radio dial.
-- The carrier wave and the voice or music waves are passed through some non-linear
device, where the frequencies get mixed.
-- What comes out is the (carrier frequency alone), (music frequency alone), sum of the
(carrier + music) frequencies, difference of the (carrier - music) frequencies.
-- The transmitter sends out the narrow cluster of (carrier alone), (carrier + music), and
(carrier - music) frequencies. The (music frequency alone) is filtered out and discarded.
Now go to the crystal radio:
-- The wire antenna catches some of the radio waves as they fly by, and conducts them
down to the "radio" set.
-- Flowing down the wire are separate signals at different frequencies. There
are the (carrier frequency alone), the sum (carrier + music) frequency, and the
difference (carrier - music) frequency.
-- All of them are sent through the "crystal", where the frequencies mix. The original
frequencies come out, along with the sum and difference of each pair.
-- Out from the crystal come these frequencies:
The originals: (carrier alone), (carrier + music), (carrier - music)
The sums: (carrier + carrier + music), (carrier + carrier - music), (2 x carrier)
The differences:
(carrier - carrier - music) = -music
(carrier - carrier + music) = music <==== ! ! !
(carrier + music - carrier + music) = 2 x music
Almost hidden in this pile of many electrical signals is one that's a copy of the original
music signal ... exactly what came from the microphone back at the studio, and got
mixed with the carrier for transmission.
All of the other signals that come out of the crystal are filtered out and discarded,
and just the "music" signal alone goes to the headphones ... "for your listening
and dancing pleasure", as they used to say in the days when the crystal radio was
about the best that everyone had.
Why Did The Grand Ole Opry get started?
Country music has basically been the music of rural America. However, in the 1920's, through the use of radio, country music was getting a bigger audience in towns and big cities across the country as well.
The creation of the Grand Ole Opry is credited to George D. Hay, who was an inventor and promoter. He became a member of the Country Music Hall of Fame in 1966.
The radio show was created to give people all across the country the chance to hear live performances by those artists who recorded the hits that they heard on the radio. The popularity of the Grand Ole Opry spread like wild fire. Soon, the Grand Ole Opry would become known as one of the "Great Institutions of Country Music."
The Grand Ole Opry will celebrate it's 83rd birthday, in October 2010. It holds the record for the longest radio show in history, and I don't think that record is ever gonna be broken!
What kind of waves are gamma rays and radio waves?
Radio waves are electromagnetic waves and are a part of the electromagnetic spectrum. Other electromagnetic waves in the electromagnetic spectrum are microwaves, visible light, infrared, ultraviolet, x-rays, and gamma rays
Where is the fuse for the radio on Renault clio?
I have the same problem, sounds like there is one fuse for both the cigarette lighter and the radio. If this has blown, the radio will run from the battery power supply rather than the ignition, therefore only giving you 20 minutes before it automatically turns off. When I get chance im going to try changing the fuse and see if it works.

How do long wave radio signals get back to an aerial?
As long as a radio signal is shooting from one place to another through space, it's
a wave of electromagnetic fields. Once it hits an electrical conductor ... like a piece
of wire that happens to be part of an antenna (aerial) ... the electromagnetic fields
set up a small electric current in the conductor, and the signal has been "captured".
That small electric current runs directly into electronic equipment that's used to make
the current stronger, pick out the one single frequency from all the hundreds or
thousands of separate signals that have set up currents in the antenna as they
passed by, then make that one stronger again, and eventually strip the information
from it, and use the information to reconstruct the sound of a song, the voice of
a newscaster or a cellphone caller, a TV picture, the data off of the Wifi in your
house, or the data from ten different satellites for the GPS unit on your dashboard.
One of the primary goals of the art and science of antenna design is to squeeze
the maximum antenna current out of that incredibly weak electromagnetic signal
as it flies by.
How do you put radio code in civic 1997?
you enter the code (4-5 digits) on the radio face usuing the preset radio station buttons. if your display reads code error you need to unplug the 40a aux fuse under the hood. it is in a little black box next to the battery. i have been told the security code will be under the lid of this box or in your owners manual. it was not on mine. if you do not have the code i was told you have to take the car into a dealership to have it reset. you enter the code (4-5 digits) on the radio face usuing the preset radio station buttons. if your display reads code error you need to unplug the 40a aux fuse under the hood. it is in a little black box next to the battery. i have been told the security code will be under the lid of this box or in your owners manual. it was not on mine. if you do not have the code i was told you have to take the car into a dealership to have it reset.
How do you reset your 1991 Honda Accord radio code?
found at http://en.allexperts.com/q/Honda-Repair-814/2003-Honda-Accord.htm
The following directions is how I got my radio to work again after having the battery changed.
Leaving the radio off at this point
Turn the car key over without turning the engine on
Before turning the radio on press and hold down 1and 6 at the same time
While holding down 1 and 6 turn the car radio on
The car radio message will still read "Code"
Stop holding down 1 and 6 (this unlocks the anti-theft device
Now just enter the car radio's code.
My radio-code for a 1991 Honda Accord is 35511
The radio will just come on
Note: You only have 3 chances before the anti-theft device locks you out so follow the directions. If you have already tried several time and the above directions don't work then drive it for awhile and wait until the next day then try again, which is what I ended up doing and it worked perfectly. I thought that when I held down 1 and 6 that some magical new code would appear but it did not, the car radio still read 'Code" so don't worry that no numbers appear. Holding down 1 and 6 releases the anti-theft device
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
What time does radio shack close on Sunday?
Their hours are not uniform throughout the chain. Each store manager has
a lot of leeway regarding the hours he keeps. You'd have to check with the
individual store. (You can do that on-line, as there is a common website for
the whole chain, where each store lists its hours.)
How do you take out a radio from a 2003 Nissan Micra?
As a previous techy for Nissan i have done this many times.
Ensure you have a radio code beforehand though, once you unplug the set, you will need to input a new one when you put it back in.
The following set of instructions is for the latest shape micra, the "bug".
1. Open both front doors
2. Remove the door seals
3. Remove the dash top by pulling upwards
4. Remove the bracket from under the dash top bolding the radio in (3x10mm bolts). make sure you don't drop these as they are quite awkward.
You don't take the radio out as a single unit, you take the radio, trip computer and vents out as one unit.
5. Remove the plasstic caps inside the little compartment at the top, and remove the two screws.
6. Remove the two screws UNDEREATH the section of trim you are going to remove, just above the heater controls.
7. Pull the radio along with everything else out as one.
8. Remove all connectors ensuring you remember where they go.
9. Put everything you have removed on a carpeted table to stop scratches, and gently remove the vents by pressing the clips back that hold them in place.
10. You can now access 4 screws that hold the radio into the frame, remove them as well as loosening as many screws as you can see that hold the together, i remember i used to loosen a certain 4.
11. With the frame loosened it is now possibe to remove the radio from the frame, otherwise its too tight.
Hope that helps,.

Can radio waves travel through glass?
Yes, radio waves are a form of electro magnetic wave. Visible light is also a form of electro magnetic waves. Visible light can be seen through glass, just as radio waves can travel through glass.
How do you remove radio from Hyundai Coupe?
1. Pop out cup holder in console. Remove the 2 screws that you can see inside. 2. Now you can pop off the entire console bezel. 3. Next remove glove box by popping out the 2 black clips on each side of the glove box. The glove box will now fold down out of the way. 4. Behind glove box remove heater wire control cable. 5. Now look under drivers side dash just above gas pedal. There are 2 more heating control cables that need to be unhooked. 6. Now the entire console bezel will pull forward. 7. Disconnect electrical cables from dash clock, hazard lights, defroster, AC and fan control. 8. The bezel will now completely come off. 9. Remove 4 screws holding radil
Note: The above answer is great and very thorough. I found that just going to step 2 was enough to remove my stereo, so check this first. Also, the bezel refers to the smooth part of the dashboard with the hazard light button, heater controls, air vents, clock, etc. A good way to pop it off is by gently inserting a flathead screw driver in a few places and turning.
How do you get radio air play for your song?
Try seeking out a PR firm for musicians, there are quite a few out there. You might also want to hire a manager on a commission basis to help deal with PR for your talents. You will want to have demo CDs and promo material mailed directly to DJs and need a list to send the promos to as well. Try locally first and build your reputation from there.
Radio does not work town and country?
You need to be more specific.
Is it a hand-held radio, car radio, stereo radio, etc?
What do you mean by "not working?" - Doesn't turn on? Doesn't pick up stations?
Re-ask with more information. There are hundreds of things that can go wrong.
Using the information given in the question, the only possible answer is: Because it's broke.
